graph-operations1: Simple operations on undirected and directed acyclic graphs.

Description

Make operations on undirected and directed acyclic graphs.

Usage

as.adjMAT(object)
ancestors(set, object)
ancestralGraph(set, object)
ancestralSet(set, object)
children(set, object)
closure(set, object)
edgeList(object,matrix=FALSE)
nonEdgeList(object, matrix=FALSE)
vpar(object)
is.complete(object, set)
is.decomposition(set, set2, set3, object)
is.simplicial(set, object)
parents(set, object)
simplicialNodes(object)

Arguments

set, set2, set3

Vectors of sets

object

A graph nel object

matrix

If TRUE the result is returned as a p x 2 matrix; otherwise as a matrix list.

Details

Notice that as.adjMAT(g) does the same as as(g, "matrix") but as.adjMAT() is considerably faster.
